This inventionrelates to heel-attaching ma-' chines and is particularly, butflby no meansexclu- 'sively, concerned with machines: for. securing wooden Louis or like heels to shoes hen attaching Louis or similar heels of wood to shoes, it is desirable for thejburpose of ob-' taining a close fit atthe crease betv veen the heel and heel-seat of the shoe, that} the nails or other as possible to the edge o' f the heel without emerging from theperipheral'zportion thereof.
